I WASHING MACHINE CYLINDER Fi y 1929 2. Sheets-Sheet 2 Patented Feb. 9, 1932 UNITED STATES PATENT oFFicE] JAMES .H; SKITT, F PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO SMITH, DRUM & COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYL- VANIA WASHING MACHINE CYLINDER Application filed May 1, 1929. Serial No. 359,457.

My invention relates to washing machines of the usual kind in which a rotary cylinder divided by partitions into compartments is 6 rotated in a suitable casing. The object oi: my invention is to provide for an improved construction of the cylinder and more particularly of the partitions dividing the cylinder into compartments and my invention consists, generally speaking, in forming the partitions of sheet metal plates secured at their outer ends to the shell of the cylinder in any convenient way and secured together at the center of the cylinder by means of interengaging folds of the sheet metal partitions.

My invention will be best understood as described in connection with the drawings, which illustrate a washing machine cylinder provided with my improvement and in which Figure 1 is a cross sectional elevation of the cylinder. I

Figure 2 a longitudinal central section through the cylinder.

Figure 3 an enlarged drawing showing the 5 interengagement of the partition plates, as

shown in Fig. 1.

Figure 4 is an enlarged drawing showing the construction of the joints formed by the partitions with the plates of the shell.

Figure 5 a sectional elevation showing a modified construction of the joint formed by the partition plate with the plates of the shell.

Figure 6 shows a modified construction of the joints formed between the partition plates at the center of the cylinder and Figure 7 shows still another modification of the joints formed between the partition plates and the center of the cylinder.

A, .A indicate the end plates of the cylinder; B, B, etc., the plates forming the shell of the cylinder, these plates, as shown, having at one end hook like folds indicated at B by which they are united together, alternate plates having at their other ends outwardly folded flanges B and folded over ends as indicated at B The joint, as best shown in Fig. 4-, is made up of an angle plate C, having an outwardly extending flange G a U- shaped clip I), having a flange D and a bolt 50 E extending through the assembled parts and the engaged end of the partition plate F, as shown.

In the modification shown in Fig. 5, the

shell plates indicated at b are formed with Two other partition plates F F are provided, secured to the shell in any convenient manner and having inner ends F which project into the folds of the S-like bend of the plate F, so that when all the folds are clamped together the partition plates are all firmly interengaged with each other toward the center of the cylinder, forming at their junction a composite strut of great strength and rigidity.

In the modification illustrated in Fig. 6, the inner ends of partition plates F general ly similar to those shown in Fig. 3, are interengaged by U-shaped folds of the inner ends of partition plates F, the U-shaped ends be ing indicated at F 5 and engaging with the ends of the plates F and with each other, as clearly shown in the figure. This modification also provides a strong strut at the center of the cylinder and a firm anchorage for the inn-er ends of the partition plates.

The modification indicated in Fig. 7, is adapted for use where the cylinder is to be divided into only three chambers by partition plates. In this construction an angularly bent plate F is bent at its center into the form of a U with double walls, as indicated at F and a second partition plate indicated at F has its center end engaged and clamped by the U F. Here again a strong strut is formed by the union of the plates at the center of the cylinder.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is:

A washing machine cylinder comprising a shell having a series of radially disposed sheet metal partition plates connected to the shell at their outer ends and connected together at their inner ends along the central 5 axis of the cylinder, at least one of said plates at its end being formed with a loop, the parts of which rigidly contact and secure there-between the inner end of at least one other partition plate.
